NEW UNITS OF MEASUREMENT
Technicians have long since tried to establish an internationally standardized system of
measurements. In 1960 a decision was made to use a system called SI (Systéme International
d’Unites). To a large extent, this system is based on earlier systems but the units have been
made uniform so that no conversions are necessary.
The SI-system is now being applied within industry in Europe, This manual contains the new SI-
units. The units used previously however, are also stated but in brackets.
The new units are:
Output is slated in kW (kilowatts)
earlier unit h.p. (horsepower)
Torque is stated in NM (Newton-metres)
earlier unit kpm (kilopond-metres)
Engine speed is stated in r/s (revolutions per second)
earlier unit r.p.m. (revolutions per minute)
Displacement and volumes are stated in dm
3 (
cubic decimetres)
earlier unit l (litres)
Pressure is stated in Pa (Pascal)
earlier unit kp/cm
2
(kiloponds per square centimetre).
